AT24C256 EEPROM Writing to a page at a time with Arduino


See the sketch on my GitHub page here.

The At24C246 EEPROM  can be used to add a few bytes of permanent memory to an Arduino project. Although there are a total of 256 bytes available, this is arranged in pages of 32 bytes  you cannot save a character across a page boundary. There is an excellent description and instructions for use on the Hobbytronics website here.

This memory can be used to store setting for a clock etc, that can be loaded into the Arduino as it powers up
